Clicks on phishing sites, insecure databases, and fake-fund wire orders are accepted without suspicion. These are not anomalies. They are the number one cause of data breaches across sectors and continents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The figures prove it. <a href=\"https:\/\/www.ibm.com\/reports\/data-breach\">IBM&#8217;s Cost of a Data Breach Report 2025<\/a> states that the average breach cost worldwide is $4.88m, and for US-based companies, it is $10.22m. The human factor was seen in 60% of confirmed breaches in <a href=\"https:\/\/www.verizon.com\/business\/resources\/reports\/dbir\/\">Verizon&#8217;s 2025 Data Breach Investigations Report<\/a>. Even more worrying is that, according to Mimecast&#8217;s State of Human Risk 2025, only 8% of employees are responsible for 80% of all security incidents within an organization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"error\">More budget. Better tools. And yet breaches continue to grow. The gap is not technical. It is human.<\/p>\n\n\n<style type=\"text\/css\">\n      @media print, screen and (max-width: 63.99875em){\n      .tnp-submit\n      width: 48%;\n      }\n      .wp-block-tnp-minimal{\n      padding: 20px;\n      }\n      .blog_para\n      margin-top: 4px !important;\n      line-height: 25px !important;\n      font-size: 15px !important;\n      }\n\n      }\n      .blog_para{\n      font-family: jost,sans-serif;\n      margin-top: 14px;\n      margin-bottom: 30px;\n      color: #fff;\n      font-size: 15px !important;\n      color: black !important;\n\n      }\n\n      .wp-block-tnp-minimal{\n      padding:20px;\n      border: 1px solid grey;\n      }\n\n      .tnp-submit a{\n        background: #1d58c7!important;\n    border-radius: 5px!important;\n    text-transform: inherit!important;\n    padding: 8px 25px!important;\n    font-weight: 600!important;\n    color: #fff!important;\n    width: 30%!important;\n    border: none;\n      }\n\n      .blog_get{\n      font-size: 24px !important;\n      font-weight: 700;\n      padding-bottom: 0px;\n    font-family: 'Poppins' !important;\n      margin-bottom: 0px;\n      margin-top: 0px;\n      margin-bottom: 0px !important;\n      color: white;\n          line-height: 30px;\n          color: white;\n      }\n      .row{\n             display: flex;\n    flex-wrap: wrap;\n    flex-direction: row;\n    padding: 25px 0px 25px 36px;\n    align-items: center;\n\n      }\n\n.colLeft{\n         flex-basis:50%;\n    -webkit-box-flex: 0;\n    flex-grow: 0;\n    max-width: 50%;\n    color: white;\n}\n    \n .colRight{\n       flex-basis: 45%;\n    -webkit-box-flex: 0;\n    flex-grow: 0;\n    max-width: 50%;\n }\n\n.tnp-subscription-minimal{\n    float: right;\n}\n<\/style>\n<div style=\"max-width: 741px; margin: 0 auto; background-image: url('https:\/\/awareness.threatcop.ai\/marketing\/linkedinlowerbanner.webp'); background-repeat: no-repeat; background-size: cover; background-position: center; \">\n<div class=\"row\">\n<div class=\"colLeft\">\n<p class=\"blog_get\" style=\"font-family: 'Poppins' !important; color: white !important\">Subscribe to Our Newsletter On Linkedin<\/p>\n<p class=\"blog_para\" style=\"font-size: 16px;font-family: 'Poppins' !important; color: white !important; margin-top: 10px; margin-bottom: 28px;line-height: 25px;\">Sign up to Stay Tuned with the Latest Cyber Security News and Updates<\/p>\n\n<div>\n<div class=\"tnp\" style=\"margin-bottom: 10px;\">\n            <form action=\"https:\/\/threatcop.com\/newsletter-thank-you\" method=\"get\" target=\"_blank\">\n<div class=\"tnp-submit\">\n                  <a class=\"libutton\" href=\"https:\/\/www.linkedin.com\/build-relation\/newsletter-follow?entityUrn=7062043746430783488\" target=\"_blank\" rel=\"noopener\">Subscribe<\/a><\/div>\n<\/form><\/div>\n<\/div>\n<\/div>\n<div class=\"colRight\">\n<div>\n<div class=\"tnp tnp-subscription-minimal \">\n            <img decoding=\"async\" src=\"https:\/\/awareness.threatcop.ai\/marketing\/newsletter-icon.webp\" class=\"img-fluid\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Human_Errors_in_Cybersecurity_Keep_Happening\"><\/span>Why Human Errors in Cybersecurity Keep Happening<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing what the realistic threats to workers already make possible is equally important as identifying the common mistakes employees commit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Three factors drive most human errors in cybersecurity:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cognitive overload. <\/strong>Staff are inundated with hundreds of emails, requests, and decisions every working day. It is impossible to study every single communication in detail. Attackers know this. Phishing emails and Business Email Compromise requests are crafted to arrive in the moments when we are the least alert. Keepnet Labs research suggests 51% of staff make security mistakes when tired.<\/li>\n\n\n\n<li><strong>AI-assisted attacks.<\/strong> This is something new. The phishing mail of 2025 no longer has the grammatical errors that at least some of us used to notice. AI-generated messages are grammatically correct, conversational, and personalized. Voice cloning and deepfake videos make impersonation attacks look no different from the real thing. The threshold at which we are deceived has come down greatly, whether someone is skilled or not.<\/li>\n\n\n\n<li><strong>The awareness-action gap.<\/strong> Many organizations realize the risk. Many organizations are effectively managing that risk. Mimecast discovered that while 96% of organizations realize their defenses are not perfect, only 28% combine ongoing staff awareness training with continuous monitoring. Knowledge is not the same as readiness.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These three factors show why these five examples below occur within well-equipped organizations. This is not a startup or a small business, but an existing business with already implemented security measures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Do_Security_Breaches_Occur_The_Most_Common_Human_Errors\"><\/span>How Do Security Breaches Occur? The Most Common Human Errors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Security breaches may not originate from malware. Most of all starts with a behavior gap.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The greatest human mistake, which is most often exploited, takes the form of phishing. Employees end up clicking on fake links or attachments, giving the hacker their credentials or even direct access to their system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Business Email Compromise (BEC) attacks<\/strong> accounts and financial and accounting staff with fake e-mails or the identities of hidden individuals to force staff to transfer funds. According to the FBI IC3 Report 2024, BEC attacks Cost $2.77 million in just one year.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Misconfiguration<\/strong> is to leave data lying around, putting files in the wrong location, leaving cloud storage accessible to everyone, or setting the wrong access levels. Verizon has shown that misdelivery and misconfiguration account for over half of the reported errors in the breach datasets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Weak or reused passwords<\/strong> enable mass credential stuffing and account takeover. According to IBM, stolen credentials are involved in 53% of data breaches and are detected on average 292 days later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Unpatched systems<\/strong> expose known vulnerabilities to exploitation. Attacks on unpatched systems are often quick once a vulnerability is publicly disclosed and an attacker is looking for one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Major_Cybersecurity_Breaches_Caused_by_Human_Error\"><\/span><strong>5 Major Cybersecurity Breaches Caused by Human Error<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\">There have been numerous high-profile cyber attacks and security breaches caused by human error, bringing several renowned organizations to their knees. So, here are the top 5 examples of how a reckless mistake costs a successful company so dearly.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><span class=\"ez-toc-section\" id=\"1_Strathmore_Secondary_College\"><\/span><b>1. Strathmore Secondary College<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\">In August 2018,\u00a0an employee at Strathmore Secondary College accidentally published student records for more than 300 students on the school\u2019s intranet, which is accessible to all <\/span>students and parents.

Technical controls reduce the impact when errors still occur. Both are necessary. Neither alone is enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Security Awareness Training<\/strong>: <a href=\"https:\/\/threatcop.com\/threatcop-security-awareness-training\">TSAT<\/a> runs simulated phishing, vishing, smishing, and ransomware campaigns that test employees under realistic conditions. Employees who fail a simulation receive immediate, targeted training at the moment of failure, when retention is highest. Research shows that consistent security awareness training reduces phishing click rates by up to 86%. Threatcop LMS supports this with role-specific modules, assessments, and measurable vulnerability tracking across departments, so leadership can see risk reduction over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>DMARC and Email Security<\/strong>: <a href=\"https:\/\/threatcop.com\/tdmarc\">TDMARC<\/a> prevents attackers from sending email using a trusted domain by enforcing DMARC, SPF, and DKIM authentication. It gives organizations full visibility into who sends email on their behalf and blocks unauthorized senders at the source. Both Toyota Boshoku and Leoni AG were compromised through domain spoofing. DMARC closes that entry point directly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Multi-Factor Authentication<\/strong>: Microsoft reports that MFA blocks 99.9% of automated account compromise attacks. Passwords get stolen. MFA ensures that a stolen password alone is not enough to gain access. It should be mandatory for all accounts, especially those with financial or administrative access.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Zero Trust Architecture<\/strong>: Zero Trust removes the assumption that anyone inside a network is automatically trusted. Every access request is verified continuously, regardless of origin. Unusual behavior, such as an unexpected login location, bulk data download, or an out-of-pattern fund transfer, triggers alerts in real time. This does not rely on an employee recognizing a threat. It catches what humans miss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Phishing Incident Response<\/strong> Threatcop TPIR gives employees a one-click mechanism to report suspicious emails immediately. Fast reporting is one of the most underrated controls in cybersecurity. The faster a phishing email is flagged, the faster it can be neutralized across the entire organization before others open it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Prevent_Cybersecurity_Breaches_Caused_by_Human_Error\"><\/span>How to Prevent Cybersecurity Breaches Caused by Human Error<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The five cases above were not caused by inadequate technology. They were caused by people who were either untrained, deceived, or operating without guardrails around their actions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stopping human errors in cybersecurity requires two things working together: a trained workforce and technical controls that catch the mistakes training does not prevent every time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Continuous, role-based training replaces annual checkbox sessions with relevant, ongoing education. Finance teams practice spotting BEC attempts. IT teams train on misconfiguration and phishing. Executives receive targeted awareness for whaling and CEO fraud attacks. Generic training leaves specific teams dangerously exposed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A blame-free reporting culture is often the difference between a contained incident and a full breach. Employees who fear punishment delay reporting mistakes. That delay turns a manageable error into a catastrophe. Fast, honest reporting consistently limits breach impact. Build a culture where reporting is rewarded, not penalized.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Technical controls that do not depend on humans to work. MFA, DMARC, PAM, and Zero Trust function whether an employee is distracted, tired, or deceived. These are not replacements for training.

It covers phishing, vishing, smishing, ransomware, and WhatsApp-based threats using attack scenarios built around current methods, not outdated templates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Paired with Threatcop LMS, organizations build a <a href=\"https:\/\/www.threatcop.com\/threatcop-security-awareness-training\">continuous learning environment<\/a> using advisories, videos, newsletters, and role-specific quizzes.
